Maintenance instructions
Inspections and maintenance performed
professionally and according to a regular
schedule as well as the use of original spare
parts are of the utmost importance for fault-
free operation of the boiler and to guarantee
its long life.
The appliance must be serviced according to
the indications stated herein, and in accord-
ance with local legislation and/or regulations.
Failure to perform Inspections and Main-
tenance can entail material and personal
damage
We therefore recommend stipulating an inspection or mainte-
nance contract.
Inspections help to determine the actual status of the appliance
and to compare it with the nominal status. This is done through
measuring, controls and observation.
Maintenance is required to eliminate any differences between
the actual status and the nominal status. This is normally done
by cleaning, setting and replacing individual components subject
to wear.
Maintenance intervals and their extent are determined by a
specialist based on the status of the appliance ascertained
through inspection.
Inspection and maintenance instructions
To assure long-term functioning of your appliance
and to avoid altering its approved status, only
original Unical spare parts must be used.
Before proceeding with maintenance, always
perform the following operations:
• Isolate the appliance from the electric mains by means of
an isolated device with a contact opening of at least 3 mm
(e.g. safety devices or power switches) and make sure that
it cannot be re-connected accidentally.
• Close the supply gas shut-off valve to the back-up boiler,
upstream of the boiler itself.
• Close the shut-off valves on the heating flow and return pipes,
as well as the cold water inlet valve.

must be disposed of in accordance with legislation in force.

there is no return of combustion products during operation.
• in case of any faults, the following must be checked:
- the air inlets are working correctly
- that the chimney draught is correct
- that the difference in pressure between installation room
and outdoor environment is greater than 4 Pa.
• the professionally qualified technical personnel will issue a
service report to the user, indicating:
- any parts that have been replaced or installed
- any remarks, strong advice and requirements
• the user must store the report carefully together with the
documents supplied with the appliance so it is available for
future use.
